Add ability to set a custom name for CSV file

[rakvium]

I haven't find an option to customize a name in the normal way, so I incidentally did some code like this:

module ActiveAdmin
  class ResourceController < BaseController
    module Streaming
      def csv_filename
        return 'User Details.csv' if resource_collection_name == :users
        super
      end
    end
  end
end

Could you please provide such an option if you have some time?
P.S.: I will also be happy if you'll provide me with a more peaceful way to rename a CSV file

I just ran into this and I was able to override the csv_filename method in the specific admin page.

ActiveAdmin.register User do
  controller do
    def csv_filename
      'User Details.csv'
    end
  end
end

I realize this issue is a year old, so this might not have been possible at the time this issue was opened.
